I found myself seeking threads in these forums about different ROM's and SOT obtained. The results were way different between different users, some claim to get 2.5h SOT some 5h SOT under normal circumstances.
Under normal circumstances I never get more than 3h and I suspected that my worn battery (598 charge cycles according to "Charge Cycle Battery Stats" app) was far from the original 3000mAh.(Thats a manufacturer stat obtained in perfect conditions, real world must be around 2800mAh)
I needed to measure the capacity left in mAh,so I bought a USB ammeter power meter (Keweisi white digits, but you don't need it, I'll explain later).
Using the Power meter, to measure properly you need to avoid thermal loss and power loss when charging:
- Note 5 completely discharged at 1 or 2% battery left.
- Disconnect the Fast charge option in Android.
- From start to finish keep the note 5 Switched off.
- Use an USB low power charger, mine was charging at 0.8A
Results: 1800mah that's far from the 2800mAh(3000mAh) when new.
(Same test I'm getting 2200mAh out of the original 2800mAh on my old Galasy S5 Neo.)
You don't need USB ammeter, Android has a builtin ammeter calculator(estimation).
Today I depleted the battery (2% left) of my note 5 again (Rom based on Android 7.0) and under battery usage I added all the "Computed Power Usage" in mAh giving the next results:
mAh
557 Cell standby (I worked underground today)
333 Screen 2h53m (30% brightness and auto brightness on)
271 Device Idle
221 chrome
203 Android OS
43 Google Play Serv.
39 Androyd System
27 Youtube
20 Yahoo Mail
20 Wi fi
17 com.android.systemui
Total: 1751mAh
This result shows that the phone itself makes a good estimation of mAh juice available in you battery.
As an anecdote I run the same test that Jerryrigeverything in YT with his Note 5(6 month of use): Playing a 2k video in 100% brightness( auto brightness off) with sound and in Flight Mode(not even wifi). He gets 6h20m, I surprisingly get 6h. But those test are only worth to compare Note 5's
Conclusions(my own and humble): Surprising degradation of my battery, specially compared with the results obtained in my S5 Neo. According to "battery university" (a good scientific source of information about Lithium-Ion) I might have shorten the life of my battery abusing of the fast charge mode.

Same here, the problem is that is quiet impossible to find a genuine battery for replacement. All those on amazon and ebay are crap.

That's the next step, find a good provider and compare capacities.
What I know so far is that there's 2 different battery models:
EB-BN920ABE The most common, but most reviews complain about being 4 or 5 mm shorter, ...less volume less capacity.
EB-BN920ABA Difficult to find, It seems the original replacement according to this picture:
https://ae01.alicdn.com/kf/UTB8YQ_yanzIXKJkSafVq6yWgXXa0.jpg The original is the right side one.
I found a Canadian provider who seems serious (free of fantasy marketing) who also ships worldwide, it looks like the original, (or a extremely good copy) I'm going to take the risk and try it:
https://www.ebay.co.uk/itm/OEM-EB-BN920ABA-3000mAh-Replacement-Battery-for-Samsung-Galaxy-Note-5-N920-N920A/401346669803?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

How did it go? Those eBay batteries tend to be pretty bad in my experience.
Finally someone else is concerned about note 5 battery capacity, i replaced mine with an original one in feb 2018 from a nearby samsung service center for $40, i used Accubattery app to measure and compare the battery capacity of the old vs the new battery.
After two years of usage and fast charging enabled in all of charge sessions, the old battery was giving me 76% (2291 mAh) of the original capacity, while the new one is giving me 89% (2675 mAh) right now, the weird thing is that it was giving me 90% right when i purchased it, i dont know if this is normal or not.
As for SOT, the old battery was giving me 2.5 hours on average, with an average of 17 hours of total usage, the new one gives me 3.5 to 4 hours with an average of 20 hours of total usage (disconnect at 100% from charger and drained to 1% or 2%)
Hope you find this post helpful

I'm in the same boat as you. My battery life blows and I am looking for a decent replacement so I don't have to buy a new phone. How did that one work out for you?
So I got my phone when it came out. Wrap charged at home and slow charged(2.1amp) in car. A year plus later accubattery says I've degraded 12% about, about same when I had my Samsung Galaxy s8 plus
Just wait for at least 20-30k mAh total charge at first I started with different values, now, after +80k, i got this.
I think we can keep it until something like 80%, I mean, it is like if you could charge your phone to only the % accubattery shows, if you get for example, 90%, you can only use a real 90% of your full charge, I get 35m sot with 10%, so I lost aprox 40-45m sot due to degradation.
Don't worry, Android 11 could get better battery life.
So your about same, I had about 88,000 % but I just installed RR rom. I also noticed after 90% it takes a lot longer to charge, I know after 90 it's not the full wrap charge speed but it takes like 20 mins or so to get 100
Funny....I just installed AccuBattery a few days ago to measure the same thing. I got my phone in March 2009, and attached are my stats.
March 2009? What phone is this? The very first HTC Google phone? If so, are you willing to sell this phone? 11 years and only 12% degradation...that's phenomenal.
On a different note, I really don't thing the battery design capacity is true to it's word. I recently changed my battery to a new one and it was starting at 96%. It's all a farce

You know....I was trying for a snappy comeback for my typo, but I realized that I messed up the year AND the month. I got the phone in September 2019. Please don't ask about March. Not sure what I was thinking there.

I believe it is possible that OnePlus pre-caps charging to 80% or so of the battery's full, true capacity to prevent fast degredation, then uses software to calculate percentage with 100% being 80%. If this were the case, it would explain people using AccuBattery seeing degredation almost consistently at like 10-15% - because the phone simply won't charge that far, so the mAH additions from charging just don't add up to 4000mAH.
To add, this isn't a bad thing at all. This isn't false advertising or anything, as this would be a feature done to prevent batteries from degrading at rapid speeds.
I don't have any proof this is the case, though. Just makes sense to me. I do recommend only using the warp charger to top off during the day, and charging with a regular usb-c charger otherwise, as the warp charging speed is actually bad for the battery life in the long run.
It is fact, though, that charging from 80 to 100% requires significantly more voltage (iirc) than the previous percentages. Think of it like trying to fill a jar to it's limits - as you put more in, you have to shove things in harder and harder , until its mostly full, where putting any more in is getting difficult as there's hardly any room left. This is obviously terrible for not only the battery but also the charging port and the like.
Well after a year you can't expect it to be like brand new. Worrying to much over little things that don't matter to actual life..,.

All your points are very valid although my contention is not that. It's that a brand new battery (so brand new that it was installed at the service centre) had a life of 96%. This was shown in the oneplus diagnostic app; so where really is the 4000 mAh when a brand new itself starts at 96%
I suspect accubattery is not so accurate. Sure he can do some math to guess the actual capacity but who knows how close it is to the real thing.
One thing here: the battery is considered discharged at around 3.3 volts. This is just to protect the battery, but also it's around 5-7% capacity I'd say. Full discharge for li-ion is around 2.8-3.0 volts, but it's bad to discharge it that much.
So in conclusion, even though your battery has 4000mah, you never get to use it at it's maximum rating because that would damage the battery and render it useless in far less charge cycles than normal.
I would say a better measure is the OnePlus diagnostic app... It lists the degree of degradation under its output
Well I did accubattery when I first got phone, and it showed 3900. Ubreakifix tear down then confirmed that was the actual capicity because in the USA you are allowed to round just like diet should have no sugar but there is zero. What really makes you notice the Degradation is when fast charging takes longer to 100

So the opposite of what you said is true. A battery with a larger capacity or less degradation takes longer to charge to 100% because the kernel and software slows down the charge for the last 10-15%. The less capacity you have the less time it takes to hit "100".
I know the charge slows down after 80%, the closer to 100 the slower. When phone was new it took like 10 to 15 mins later to go from 90 to 100. Now it's taking 15 mins to go from 92 to 95. Having note 5 previously the next Degradation step is when over all charging takes even longer and the battery life is shorter
I don't even worry about battery degradation. I put a wireless receiver on my OnePlus and have wireless charging everywhere. My phone is always around 80 to 100 percent.
I'm a heavy phone user and using accubattery on this phone for a long time now. Got my phone in June 2019 and based on 636 sessions, it shows battery health at 90%. Probably because
1. I haven't charged my phone more than 80% for about 70% of sessions.
2. Because of the large data AB has, it has more accurate estimate.
3. I read that the health section itself is not accurate.
Here's mine (got it second hand in March 2020)
Should I be concerned? I just got the phone back in March new from TMobile
THROW YOUR 120W CHARGER AWAY.
Get a charger for around 65W.
Get a decently good brand. ( I'm using Anker, 65W Mi Charger is also good. )
Anything below 30W would be too slow to charge your phone. Not really practical.
Personally tested a 10W charger, did not work out for me as it doesn't give me the same battery performance.
In my opinion, Xiaomi played us on this one. The 120W charger is a marketing gimmick. I don't think it charges the phone to 100% even though it shows 100%. Either that, or it messes with the battery calibration. As soon as I charge with a 65W charger, the battery goes back to performing properly. By that I mean, lasts me the entire day, and I still have 35-40% remaining the next day on medium usage like maps, streaming. On heavy usage, it still gives me great battery.
I'm 100% sure, you will notice the difference if you switch away from 120W charger as it will drastically extend the battery.
If you have already experienced the difference or made the switch, please do share your experience. On the stock xiaomi charger provided with the phone, the battery life is really terrible, the same usage gets me barely to the end of the day.
If you're still not satisfied by the drastic difference made by the charger only.

How to increase the battery life of the Xiaomi 11T / T Pro
Hello guys, I want to tell you about the adjustments that I have made to my Xiaomi 11T Pro and that have improved battery consumption, keeping the refresh rate of the screen at 120Hz. I would appreciate if you could tell me how it went...
forum.xda-developers.com
It will be simply because it is a fast charger, incredibly fast, and you can't completely charge lithium batteries fast, there is always a slow end stage that will take an hour or more regardless of how many watts the charger is. The last top off stage, or saturation stage on lithium cells needs by definition to take time and will charge at a lower current and it has to be slower.
They are showing 100% on fast charging, but that's only the bulk charge capacity with a lot of the saturation stage not done, so you don't get full capacity. The 100% indicator is saying you've charged as much as you can fast, but it might only be 70% actually full. If it is left on the charger, it will likely wait until the temperature has dropped then continue for an hour or so completing the saturation charge, all while still indicating charging is complete, but if you remove it from the charger the moment it hits 100%, then it's not the same 100% you'd get by leaving for a couple of hours.
If they indicated 100% correctly as being as charged as it can be, it will take 20 minutes on fast charge plus an hour or two for the saturation stage to be done, so doesn't quite sell as well!
Xiaomi are cheating somewhat by saying 0 to 100% in x time on fast charge, as the definition of 100% when fast charging is changed.
Personally I just charge over night at 5 watt, better for the battery and you get full capacity.

Great insight, they should have mentioned it in a different way instead of saying it's 100% charged. But then that ain't gonna earn them any bucks.
Are you getting a good battery life on 5W? As when i was using the 10W charger and use the phone at the same time it would take forever to charge. And the battery sot wasn't as good as well compared to 65W sot for similar usage.
I also use 10w (5v 2A) and can get for about 8h of sot, charging time is in my case takes about 2:20h from 17-100%Its not that bad, and i prefere slow charging time anyway, i only use 120w when in hurry

If you are using the phone at the same time as charging, you are of course using a chunk of that 5 watts to power the phone, so whilst your battery may not be discharging, there isn't much left over to charge it up.
I always charge overnight as I easily get a day if not a few days from a single charge as I'm not using it much currently as working from home, but if you need to top up during the day whilst still perhaps using it, you would need a charger with a bit more wattage.
Also note that whilst it may say 100% charged, that could represent anywhere from say 95% to 100% actual charge. This is because lithium cells can not be trickle charged, so when charging it will get to being a full capacity, then charging stops, the battery is allowed to discharge several percent before automatically being topped up again, and the cycle continues. So depending on where in that cycle you take the phone of charge, you might be really at 100%, but could equally be at 95%. Because people would complain if the true charge status was shown, i.e. people leave the phone on charge all night and its still only showing 95% in the morning simply because it's on the discharge stage of the discharge/top up cycle when they look at it, they would complain, so 100% is shown from say anywhere between 95% and 100% of real charge state. This applies to all devices. It is why sometimes you take your phone of charge at 100% and it seems to stay at 100% for some time, and other times it starts going down soon after you've unplug it from the charger. Google on their Pixels have an adaptive battery setting and use the alarm clock you've set to know when you are getting up, so they make sure they time that cycle so that you get the phone at a real 100% capacity.
Good thread fellas. Yeah 120w it's just a thing you should use when there's not another option or your in a real rush. And by using it your battery calibration might get confused.
It's as the OP mentioned, with 120w you can feel that your battery life is shorter than charging with lower wattages.
IMO and experience I calibrated my phone's battery (drained it to 0 let it turn off , leave it unattended for around 10 min, then charge it with a 10w while still turned off if possible. And leave it charging 1h more after it says 100%) and b ayer doing so my 11t pro finally became the 2-day phone it should have been from day one.
I personally prefer to charge mine with a 18w (1h20min) or a 22.5w (1h) during the day. 10w it's just for overnight, it's just to long 2h40min or more.
This might be the reason why Samsung nor Apple has not yet jump into bandwagon of 100w-ish charging. Even not to 65w. It just my hunch though. Still, 100w-ish charging might be life changing in certain situation. And if I recall correctly, the most ideal percentage to charge Li-On is around 80-ish, that might the actual percentage that we get if we charge to 100% with 100w-ish charger.
To be honest i tried 33w charger and 120w charger and battery performance for me is the same(4.5sot + 6 background yt music)
The thing is when u use 120W charger and battery go 100% you have to let it charge 5-10 min more because is not fully charged.
You can check with app called ampere(download from playstore)

Please try a 65W charger from xiaomi or anker, i guarantee you the difference. Sot also depends on the usage, but there will surely be a drastic increase in the battery capacity.
And i completely agree to your point on trickle charging. But unfortunately, it does not justify the 4 hrs sot difference im getting after charging my phone through different chargers. 65W gives me 8 hours, whereas 120W full charge gives me around 4 hours.
I feel xiaomi really just did this as a marketing gimmick and did a half hazard job at it.

Like i previously mentioned as well in the above post, trickle charging or that 5-10% of charge shouldnt make the difference im experiencing after switching chargers. 4 hours sot difference is no joke. Its literally half battery capacity.
I love the phone, but Xiaomi really messed around with us on this.

Unfortunately i don't have a 65w charger :/
I get 4.5 sot because i also use yt music for 6-7 hours in background + 5g all dhe time.
The problem i noticed is that when i use my phone after charging my battery gives me good sot (5 hour non stop gaming mlbb and still have 25% left). But if i charge at night and use the phone the next day the battery drain really fast (that's why i charge every morning before i leave home).
I'm not really happy with battery life to be honest but im really happy with charging speed
+ How you guys get sot 8hrs?. I never couldn't do that with my phones( old device k20 pro average 5hrs sot)

Even after switching away from 120W charger, if you're not seeing a drastic difference, then i recommend changing the chargers to something similar to what i own (anker) about 65W or a mi charger 65W (official). Because i personally experienced the huge battery life change, and i know this phone can give a 1.5 day battery life on medium usage. On heavy usage it lasts me easily the entire day (8hours sot easy). But usage may vary. And when i was using 120W charger, it was giving me 4hours sot, with the same usage. So i know, the phone has the capacity to do it.
Maybe it could be a non branded charger issue? I'm not sure. It should show quick charging when charging via the different charger as well that way you know its getting the juice it requires.
Rocking a Xiaomi 67W charger and so far not much difference. I'm using the phone out of the box, I am not switching back to 60hz since whats the point of buying it if you wont use 120hz. Lets see after a few more cycles.
EDIT: After using this 67W for 2 days now, battery life is the same. IT might not be the charger but going back to 60 Hz might be the reason some ppl had improved battery life. I will return back to 120W since I prefer the ultra fast charging while the phone stays cool at the same time (mine is at 40-41 degrees C and it charges around 20 minutes)
EDIT 2: Tried 60hz for a day, since I was out with family, it noticeably improved battery life even though I charged with the 120W adapter. Hopefully Xiaomi adds a dynamicswitch feature for us soon or a 90hz option

I tried using my phone on 120hz for a day or two, i get like an hour less compared to 60hz i find a major difference in battery even with 120hz enabled.
Not sure why. But if it works, it works.
Also just to clear my experience, i never use this phone on 120hz, even when i initially was using the 120w charger. It has always been set to 60hz for me, as i like to save battery wherever i can.
Update: Using accubattery, when my phone reached 100%, its still taking in current around 1500-2000mah range (around 10-15w) and its trickle charging the battery. The estimated capacity when reaching 100% is around 2200 mah(times 2 since our phone is a dual cell battery) then letting it trickle charge for a few minutes (an extra 10) made the capacity to 2550(which is around 5100 mah) and by doing so I am easily getting 6-7 hr sot on 120HZ. It may be a marketing trick to reach 100% in an instant but leave it plugged in for an extra 10 mins or so to get more screen on time.
quite great battery life

Don't trust the apps. Find some real volt meter.

Amazing!
MIUI 13 by any chance?
I am on miui 13 official, had heavy battery drain on miui12.5, disabled miui optimizations and now everything is good
Edit: apparently the program that handles battery changed after disabling miui optimizations, maybe it's a bug related issue
I have been using my brand new Tab S8 5G for 8 days or so. I have AccuBattery installed. The estimated battery capacity has been very low from Day 1. Currently I get:
Battery Health 87%
Estimated Capacity 6759mAh
Design Capacity 7760mAh
Based on 31 sessions 1031% charged for 69688mAh
I understand it takes a few days for AccuBattery to function accurately, but I think it's been enough. The design capacity has been automatically measured and already adjusted to a lower value than what Samsung advertise (8000mAh). I've also installed 3C Battery Monitor app, but the estimate is very similar (3718). I have bought 2 other (non-Samsung) android devices in the past few months, but their estimated capacities are much closer than 100%.
Has anyone expericed the same? Or do you think mine is a bad lemon and should be returned? Any insight would be much appreciated! Cheers.
Are you charging to 100% or just 85% (battery save option). If you charge up only to 85% then it is accurate.
Thanks! That's a very good question. I have used the 85% charging limit option for a couple of days but left it off for the majority of time.
But wouldn't it be the same from AccuBattery's point of view if you used the option or not, as the tab tells the app 85% as 85% not as 100%? (or maybe my assumption is wrong).
I have since updated AccuBattery (which cleared all my history!) and started self- recalibrating the app as their website suggests (you go down as low as you can, and start charging until drawing ampere really finishes at over 100%). After a few iterations, hopefully the app will show more accurate info. (Or not, I will just come terms with it!)
https://accubattery.zendesk.com/hc/en-us/articles/213575425-How-to-manually-benchmark-your-battery-health
İ think accubattery calculates with the Design capacity of the device, with the the Option to charge up to only 85% you would have charged up to 6800mah vs. 8000mah 100%. But i could be wrong too
Just not to open another thread. I have a similar situation with my tab s8+. All apps that do something hardware/battery related report the battery to be 9800mah and not the Samsung claimed
10090.
As for now I'm letting sccubattery do its reading, but so far battery life has been ok for a tablet with high end Specifications. On average I get 8 to 9h of SoT on average not very demanding usage.
Yes my S8 has also a considerable difference between Samsung's advertised battery capacity (8000 mah) vs the capacity apps like AccuBattery read (7760 mah). That's probably their way to prevent users from overcharging their devices.
On top of it, I have also found that my tab can go quite a bit after showing 100% charged. Following AccuBattery's re-calibrating (re-benchmarking) method l mentioned earlier, in one charging episode I saw my tab going up to 8700 mah or so until it started showing 0 or negative charging values about 40 mins after it showed 100%. Having overcharged my tab a few times this way, AccuBattery now shows about 100% for battery health. Obviously this isn't a good way to charge your battery in terms of its longevity, but it might help to calibrate your new device with a battery app. When the % reaches 100%, the estimated capacity on AccuBattery is normally much lower, something like 6700 mah, as I initially got. I need to do more tests, but I find the leeway Samsung spare is a bit too much.
Interestingly, I have also found quite a bit of variability in this 'fake 100% battery' setting across different manufacturers (or at least different devices). I am applying the same recalibration process on my Xiaomi Pad 5 Pro and OnePlus 8T. They are both about 9 months old. My OnePlus behaves somewhat similarly with my Tab S8, showing about 10% extra capacity after 100%, whereas my Xiaomi really stops charging when it reaches 100%.
Hey. This is my stats on my S8+. I recommend trying to completely discharge the battery to 0%, charge to 100% and wait until current is 0 mA. Do this min 3 times in row. Then you will get a more accurate reading
Hello all,
I got my self a Find X3 Pro a few months ago and I noticed that Accu Battery Pro and Aida 64 Battery, never reach the min capacity of 4400mah or typical capacity of 4500mah
Is this thing a issue ? Or my battery is degraded from brand new ? Or is this a software incorrect reporting issue ?
Thanks in advance !
Make sure to let it charge for about 7 minutes after it reaches 100%. The phone is not actually fully charged when it reads 100.
See here, after the first charging graph
Oppo Find X3 Pro review
The Oppo Find X3 Pro employs a similar display to the one we enjoyed on the Find X2 Pro. It's a 6.7" LPTO AMOLED screen of 3,216 x 1,440 px resolution or...

Then check again the meters. If they still read 4200, then you may have a degraded battery.
Also, consider that even if the phone is "new", it may have been produced a long time ago (like a year ago or more), thus suffering from some battery degradation already.
I always make sure I let it charge for about 10 more minutes at 100%. Still between 4000mah - 4200mah it displays.
Recently I replaced the battery for an old Mi 5s Plus and after a few charges (3-4) it will show the correct mah of 3800 (~3792mah)
So, did someone actually have these apps display the correct rating of the battery ?
I will give it a try tomorrow, but my phone is 1.5 years old at this point, so I don't expect to see anywhere near 4500 for sure.
I checked mine, but only 2 cycles it showed 89% The phone is 8 months old.
Thank you for your feedback...
My phone is barely 2-3 months old, should I try for warranty ?

Try to charge slowly to 100% using a 3A cable or less and leave it in charge until Aida64 show complete charged, then check charge counter how much mah show. Normally the counter will be a little less respect to declared capacity, like for hard disk the real capacity is not the full declared capacity. My X3 pro is used and charging to 100% show less of 4000 mah but battery life isn't bad.
18 months old phone, about 84% health (only one measurement though)

I'm sorry to tell you but you are mistaken, my ex Red Magic 3 phone indicated my rated capacity for battery and my recently replaced battery for Mi 5s Plus also indicated 3792 mah out of 3800mah, so I presume the issue comes for a incorrectly stored phone when I purchased it or old batch.
I always charge slow or at 1.8A because I'm never in a hurry, I even charged it at 500mah overnight and it went to just 4115 mah out of min 4400mah

No it depend from device to device and also from update cause it change also with kernel version. When I have OnePlus 7 pro always charged slowly bu never reached the full capacity of charger counter, this changed when I tried Oxygen OS 12 India beta, the battery show 4500 in charge counter exactly like the battery capacity. So it can depend from many factors and isn't simply to understand how really battery life is.
Thank you for all of your support and answers !
Yesterday I installed Battery Guru 2.0 and seems a more decent app than AccuBattery, will keep monitoring
AccuBattery and Battery Guru 2.0 tell me that I only have 1598mAh.
Aida64 tell me 3504mAh.
I don't understand...
I only know that my battery life is poor. I arrive with 20% or less at 8:00pm.
It is also true that I have many IOT applications always active, as well for the smartwatch, wifi, BT and GPS always on and also Always On Display all the day.
Cheers.

DO not forget to check the dual cells in the settings of the apps (accu battery and battery guru)
But even so.... 1600 mah x2 => ~3200mah
Very very unusual for this phone and battery
